Haptic and optical effects on packaging

In 4-colour offset printing, all colours are achieved by the printing of small coloured dots next to and over one another. This is then interpreted as a mixed colour by the human eye. The photographic image is deconstructed into rows and chains of points via a grid resolution. These are arranged at different angles to each other. When mapping finely structured surfaces, for example, textiles and fabrics, so-called moiré effects may be created. The structures of the image are overlaid by the technical grid resulting in unattractive interference images. The use of a special anti-moiré grid may help here. We master the structure of printed images as combined grids using standard and anti-moiré elements.
